neotrope on "[Plugin: WP Mail SMTP] Problem with local email Port 573 STARTTLS"

Hi
seem to be having an authentication issue trying to send test email out via our local domain (which has SSL cert and matches the store domain, on dedicated server).

Is there anything we need to do ensure STARTTLS is instantiated?

Thanks for any pointers.

We need to send email "from" our own domain so it looks like we're sending it, not out through gmail or some outside mail system.
